SOURCE: 1998 Cadillac Deville low refrigerant a/c

I have a 1999 Cadillic Deville. The low Frefrigerant indicater come on after about 15 minutes of disconnecting the battery power. Each Time I reset the power the air conditioner comes back on for a while then goes out. I have taken it into the local auto repair place and they find no problem with the unit.
Could this be a intermittent connection to the computer. They have replaced both sencors and the problem persists. Where is the computer located on the car that handles this AC sensor message?

SOURCE: 1998 cadillac deville fans not coming on starts

If your fans are not coming on then your engine is not receiving the signal that it is overheating. This can be caused by bad fans (unlikely they are both out) a bad relay, or coolant temperature sensor. I would start by checking or replacing the temperature sensor as it can become corroded which is what the PCM uses to turn the fans on. Many vehicles use two sensors, one for the gauge and the other for the ECU, make sure you check/replace the right one. It should be a cheaper part and if you are unsure then match the new one with its location; it should be on the intake manifold or near it, generally with one or two wires. I think you will find your problem as they are common failed parts.

Good luck!

Cruise control will not come on

This is most likely because of a bad clock spring in the steering column. Does the horn work? this also goes through the clock spring.

Cruise control stopped working

Check the cable for the cruise control that leads from the actuator to the cable end located on a wheel that controls throttle. If this cable is broken on the driver's side, then it will not work even if the cruise control is engaged according to the dashboard's driver information center.

Cruise control schematic diagram

I have a 1998 GMC Safari van in which the cruise control has quit. It didn't go all at once. It would work intermittently. Sometimes going 5 miles or so and then shutting off and then after another few miles, it would set again. This sounds to me like something getting hot. Is there a circuit breaker for the cruise control...or?
I can't seem to find a good schematic/diagram for the unit. Driving me nuts! I don't want to have to buy a whole new module if there is a simple fix.

Cruise control doesnt work,,,i there any fuse for it? this is for a cadillac deville 94

Cadillac's of this year have been known to have the wire(s) fromt he cruise control break in the steering colum. This is due to the tilt wheel moving up and down over the years. You should be able to either repair the broken wire or get a used unit (turn signal/cruise) and wiring harnes at a salvage yard. The wiring runs along the steering column to a connector on top of the column about half way down.
Check your fuses first. I believe the cruise and a couple of other accessories are on the same circuit. Is there anything else that doesn't work? (i.e. cigarette lighter, dome lights...) If you have the owner's manual that would help OR a trip to the public library in the auto section...Hope this helps.
